Version 2 of TubeMark?

Hi @chaosifier,

sorry for the delay, I got a bit slow doing all the boring stuff like tidying up my changes ;)

I still need to update the screenshots, which I'll try later this week, but the bulk of the work is there if you want to have a look at it more closely. I know I've changed a lot here, since I wasn't originally planning on merging this stuff back to your fork, but hopefully you still like it all! If there's anything you're unsure of or don't like, please don't hesitate to leave a comment.

I'm not sure of the process for uploading the changes to the chrome web store, or if I need any permissions from you, but maybe we can aim to get it up in the next week?

Looking forward to your feedback!
